Terry, you seem to be the Toto guru. Can you help me out?
I don’t understand Toto’s specifications.
I replaced a toilet with a Toto Drake CST744S. The included instructions state that the rough-in must be at least 12 inches, which is what I have. The included drawing shows the distance between the wall and the back of the water tank lid should be 3/4-inch. Toto’s web site spec. sheet shows the distance as 1-1/8 inches.
In reality, I ended up with a distance of 2-1/4 inches from the wall to the back of the water tank lid. I contacted Toto and inquired as to the discrepancy. The Toto rep. asked for some mfg. numbers on the water closet, but none were to be found. He then suggested they should replace the water closet.
The replacement has been installed and it measures 2-1/8 inches from the wall to the back of the water tank. (These figures take into account a slight variance in the plumb of the wall and the floor is level.)
This weekend I was in a hotel that had what appeared to be the same toilet, but one that was ADA compliant. (It had a ST743S tank.) It looked very good, as the water tank lid sat very close to the wall, but they used only a 10-5/8 inch rough-in.
My next project is to replace a really old toilet that has a 12-5/8 inch rough-in. I would like to install a Toto Drake CST744S. If I do, must I simply accept a huge space between the wall and the back of the water tank lid or is there a simple fix?
Thanks for the help.
